locked in a single operation.

The main object of the invention is the provision of a locking arrangement for the doors of a motor vehicle whereby all the doors of said vehicle will be remotely connected to a central lock actuating mechanism which is operated in a single operation.

Another object of the invention is the provision of a locking s stem of the character described which is eflicient in operation and almost foolproof.

A further object of the invention is the provision of a locking system for the doors of a motor vehicle which can be installed to existing constructions and which is cheap of manufacture and installation.

Still another object of the invention provides means for looking at one time all the 1 doors of an automobile and which is readily connected to an preferred type of lock without extensive c anges.

Further objects and advantages of the invention will be apparent as the description progresses. A

As an example and for purposes of illustration, one embodiment of the invention is shown in the attached drawings, forming a part of this specification, and in which:

Figure 1 is a partial elevation view of a motor car showing the position of the lock proper,

F1gure 2 is a similar view but showing the inside arrangement,

Figure 3 is a section taken on line 3-3 of Figure 1,

Figure 4 is a transverse section through the motor car and looking towards the back thereof showin the arrangement for remotely locking 51c doors opposite from that side of the car carrying the lock,

Figure 5 is a sectionaldetailed view of the remote mechanism,

Figure 6 is a sectional detailed View of the lockin mechanism corresponding to the right and portion of Fig. 4,

Figure 7 is a similar view of the left hand portion of the Figure 4,

Figure 8 is a View taken on Fi ure 4,

Figure 9 is a section on line 9-9 of Figure 2,

Figure 10 is a section on line 10-10 of Figure 7, and

Figure 11 is a view similar to No. 3 but showing the concealed arrangement thereof as embodied for example on a new car.

In the drawings, wherein similar characters indicate corresponding parts throughout the same, the numeral 15 generally designates the body of an automobile having in the caseof a four-door closed sedan an upright post 16 between the two doors 17. At a position adjacent the door handles and in the post 16, as shown in Figure 1, a lock 18 of suitable structure and ada ted to be operated by a key is providedl This lock 18 preferably comprises a casing 19 rigidly secured to the post 16 or to the vehicle ody, and comprising a rotatable lug (not shown) having a plurality of tumlers adapted tolock said plug a ainst movement. The key 20 bein shown itted in Fig. 4 clearly indicates t e presence of said tumblers in the plug which cannot be line 88 of rotated unless the proper key is inserted in the look. In all respects, this look is identical to the locks provided in one handle of all closed motor vehicles.

A square rod 21 affords connection between the lock barrel or' plug and a member to be described presently. Directly opposite said lock, and inside the motor car, a casing 22 is secured to the body by means of a base plate 23, said casing having pivoted therein a memher 24having locking bolts 25 diametrically op osed around the pivoting pin 26.

s shown to advantage in Figure 10, said pin or stud 26 is rigidly secured to 24 and oosely mounted in the plate 23. Furthermore, said stud is chamfered at both ends to prevent its removal.

Obviously, since the lockin system is operated at one point only, it IS evident that one side of the car will receive the lock proper and actuating mechanism, while the other side will be controlled by the first. This is shown in Figures 6 and 7 Figure 7 disclosing the actuating mechanism directly connected to the lock 19 by means of the square rod 21 and for which purpose the stud 26 has a? aperture 27 adapted to receive one end 0 21.

In order that the movement of the controlling member 24 be directed to the other mechanism, a connecting link is rovided between the two, said link consisting of a chain, cord or the like 28 which is threaded over pulleys 29 disposed in the upper cornersof the body and which are concealed by a covering casing 30. Furthermore, the cord 28 is disposed inside a protecting metal channel 31 which is slightly flattened for purposes of appearance and is secured to the body by cleats 32.

In order thatthe movement of 24 be readily transmitted to the cord 28, a connecting member 33 is provided and which is pivoted on 24 at 34 acting somewhat like a crank. Said member is connected at 35 to the cord 28 by any suitable means.

This comprises the actuating end of the system. 7

The other end is substantially similar with the exception of a spring 36 disposed between a stop 37 and an enlargement 38 on the crank 39 of the actuated bolt 24. The spring is thus limited to the sole function of retract,

ing the crank 39 when the cord 28 is slack' ened. From the foregoing, it will be readily realized that whenever the controlling member 24 is rotated by means of 21, in unlocked or looking position, the lever 33 will either exert a pull on the cord 28 against the action of 36, whereby the other member 24 will be actuated in looking position, or instead, the cord 28 is loosed by the movement of 33. In this last instance, the slack of 28 is taken up by 36, whereby 24 will be moved to the limit of its travel, into unlocked position, through the instrumentality of 39.

An inspection of Figures 6 and 7 will readily disclose the fact that whenever the member 24 is turned in a clockwise direction the bolts 25 will protrude outwardly from the sides of the casmg 22.

To complete the system, a suitable bolt receiving socket 40 is provided on each door to be locked, the same being shown in Figures 2, 3 and 11.

' From the foregoing, it will be readily realized that the present invention offers a most simple and eflicient means for simultaneousl locking the doors of a motor car. Evident y, in the case of so called coaches, or cars having a total of two doors only, the application is substantially the same with the difierence that the block 24 comprises one bolt only.

It is to be understood that the form of my invention herein shown and described is to p be taken as a preferred example of the same,

hand.

each door, a rotata 1e member in each of said' casings, a pair of diametrically opposed bolts on said member adapted to enter sockets on the doors, a crank on each rotatable member pivoted eccentrically relative to the axis thereof, means connecting together the said cranks, and key operated mechanism for actuating one of the rotatable members.

2. In a device for simultaneously locking the doors of a motor Vehicle when operating the lock of a single controlling door, a. casing secured adjacent each door, a member rotatably secured in each casing and comprising .bolts adapted to protrude from the casingwhen the member is rotated, and into sockets on the door, an ofiset crank pivoted on each member eccentrically relative to the axis thereof, a flexible-connecting link'between the member cranks of each door and that of the controlling door, concealing means for said connecting link, a spring for urging therotatable members of the controlled doors whereby the bolts assume a casing-retracted inoperative position, and key and lock actuated means on the controlling door to secure said members against the action of the spring in a door locking position.

In witness whereof I have hereunto set my ERNEST VIGEANT.
